Audigy soundcard silent after upgrade to Ubuntu Studio

[David Morrell]

Problem solved by a contributor on LAU.

He sent me a /var/lib/asound.state file from a working Audigy2
installation and, what do you know, it worked.

There is a file that describes the state of the sound card in
/var/lib/alsa/asound.state. When the original (bad) version was replaced
with one from a working Audigy2 sound cared (good version) the card
started working.


The replacement asound.state file has 227 controls vs 216 for the oroginal.

The following 14 switch controls existed only in the good file.

The Master Playback Switch only existed in the good file. If it exists
on the sound card and is muted by default, there would be no sound output.

There are 3 possible duplicated controls.
